A step has three properties that define how it will be treated by the algorithm running engine: Tag: unique identifier of a step, typically the name of the function associated with this step, followed by a numeric index accounting for possible multiple uses of the same function; Active: a Boolean (true/false) value indicating if this step is to be considered or not when running the algorithm (to allow maximum flexibility in testing algorithms); InParamLinks: a list of strings linking this step functions parameters to values returned by functions in previous steps, wherever the case (not a typical situation, but implemented for flexibility). Feature extraction refers to the process of transforming raw data into numerical features that can be processed while preserving the information in the original data set. Hough transform: It defines an efficient implementation of template matching for binary templates.
